US District Judge T. Kent Wetherell II upheld the Treasury Department’s decision to sanction crypto mixer Tornado Cash, striking down a challenge from crypto advocacy group Coin Center. Judge Wetherell found that the Treasury Department had not exceeded its authority when issuing the sanctions. The Treasury Department sanctioned Tornado Cash in August 2022, after finding that the crypto mixer had laundered more than $7 billion worth of virtual currency since its creation in 2019.
